The number of sisters Anna has is twice the number of brothers Anna has.


Does Anna have any siblings?


To solve this problem, we need to analyze the given statements and determine if they lead to a contradictory situation or if they provide a valid solution.

Given information:

  • The number of brothers Anna has is twice the number of sisters Anna has.
  • The number of sisters Anna has is twice the number of brothers Anna has.

Let's represent the number of brothers as x and the number of sisters as y.

According to the first statement: x = 2y

According to the second statement: y = 2x

Substituting the value of x from the first equation into the second equation: y = 2(2y) y = 4y

Simplifying the equation: 0 = 3y

The only solution to this equation is y = 0, which means Anna has no sisters.

Substituting y = 0 into the first equation: x = 2(0) x = 0

Therefore, Anna has no brothers as well.

Conclusion: Based on the given statements, Anna does not have any siblings.
